Interest in such micro-UAVs is increasing worldwide, due to a growing number of potential defence and civil applications. Ultra Electronics believes that the engine’s ability to operate on both kerosene (JP8) and gasoline will make it suitable for either defence or civil operations.

Kevin Hurst, Ultra Electronics Precision Air Systems sales and marketing director, said: ‘We are delighted to have reached agreement with RCV to bring this product to market. Its excellent fuel efficiency and dual-fuel capability will offer UAV operators significantly increased mission endurance and the logistics benefit of being able to use either JP-8 or gasoline fuels.

‘We are currently working with RCV to develop an electronic engine management system and production units will be available early in 2010. We will be displaying the engine on our stand at the Paris Airshow.’
